Low-noise pneumatic tire

The invention discloses a low-noise pneumatic tire. The low-noise pneumatic tire is characterized in that sound absorbers are arranged in an annular tire cavity formed by the inner surface of a treadand a rim, the sound absorbers are single bodies in a rotating body shape, the multiple sound absorbers are arranged in the tire cavity at equal intervals in the circumferential direction of the tire,and the sound absorbers located at the radial symmetrical positions of the tire are single bodies with the same density and appearance to form radial symmetry. According to the invention, noise generated by cavity resonance of the tire can be effectively reduced, and vibration energy of the tire during driving can be reduced. 本发明公开了一种低噪音充气轮胎，其特征是：在由胎面内表面和轮辋共同形成的环形轮胎空腔内设置吸声体；吸声体为具有旋转体形状的单体，多个吸声体在轮胎空腔中沿轮胎圆周方向等间隔布置，处在轮胎径向对称位置上的吸声体是密度和外形相同的单体，形成径向对称。本发明能有效降低轮胎因空腔共振所产生的噪音，并降低轮胎在行驶时的振动能量。
